Like characters of reference designate like parts in the several figures of the drawings.

Referring to the drawings, vand particularly to Fig. 1, 25 designates the glass furnace haring a working opening Q6.

The glass forming machine comprises a rot-ating framework 27 on which the glass blowing spindles 28 andthe other operative devices of the machine are supported. This framework is provided with a circular rack or gear 29 and is mounted on a. circular base 30 supported on a -base plate 3l. The base platc'is supported on shafts 32 carried in hearings in levers The levers 'lulcrum at one end upon the axles oi' wheels 34, 84

(Fig. G) which run upon tracks 351. The

anced by means of weight'sf) supported'on cables 40 anchored to the hase plate at 41- and extending around the sheaves 38 and similar sheaves 4Q on the hase plate.. The threaded shafts Si?. 37a (shown best in Fig.

15) are engaged with the hase'piate ofthe machine by means of nuts 43 which thread onto the shafts and are held from movement lengthwise of the shaft. The machine is these several movements 1s designated 47.

raised and lowered by rotating these nuts. The mechanism for doing this will be de scribed subsequently under qthe, heading Raising and lowering mechanism.

The movement of the machinev to' and.

from the furnace is accomplished by means of .acog wheel 44 (Figs. 3, 6 and 13)'whicb engages with a rack rail 45. y The mechanism for .driving the cog' wheel 44 will be hereinafter described under theV heading Mechanism for moving the machine to and from the furnace.

The rotation of the frame 27 is accomplished 'by means of a pinion 46 which meshes with .the circular. rack 29 and is driven by certain mechanisms which will be described under the heading Mechanism foi-rotating the machine. f

The motor which sup lies power for and is carried 0nv a bracket 48 secured to the base plate 31. The armature shaft 49 of thel` motor is connected lwith the main shaft 50' (Fig. 5) of a transmission mechanism which is contained within ,a casin 51. supported on the bracket 4.8. The sha t 50 is thereforedriven at all times when the? motor is in operation. The transmission mechanism is connected with the shaftO, or disconnected therefrom, by means of what I have termed the main clutch.

The main cZutcz..-.Keyed to the main,

shaft 50 isv a clutch'member 52 (Fig. 5) (adapted to be engaged ,by a slidable clutch member "53 in which `the shaft 50 revolves when out ofengagement with the clutch' member 52. 54 designates a pinion which is slidably mounted on the hub 55 of the clutch member 53 and is held from rbtation thereon by the feather i rhe pinion 54 meshes with a' pinion 57 revolubly mounted on a ,sleeve 58' surrounding a shaft '59 mounted in bearings m the casing 51. The gear 57 lmeshes with a gear 60 revolubly' mounted on a shaft :Gl which 4turns in bearings in saidcasing;I y n Thet clutch member 53 is moved into en gage-ment with the clutch member 52, its

huh-sliding through the pinionI 54, by the following mechanism: 61 designate dogs pivoted to projecting portions (S2/of thel pinion 54. The dogs are formed Withthe an- 'gulamcams 63 adapted toA bear against a hardened metal ring G4 which in turn bears against the hub 55 of the clutchmember 53. The dogs are rocked soas to force the hub 55. through the pinion by means of a collar formed with a conical face 66.. Surrounding the collarf is'a sleeve 67pmvided with circular teeth adapted. to be meshed by vtheteeth of a sector 'gear 68 carried by'a hollow shaft 69 mounted in` a vervided between the collar 65e-nd' the sleeve 67. The collar 65 surrounds a sleeve 72 on the shaft 50.

-The sector gear 68 isiroclied forithe 'purs A pose 4of moving the collar G5 against and away from the dogs 61 by the following mechanism: 7 desi gnates-a lexf'ervthat may be termed the main clutch controlllng le.-k 'It ver-,mounted on a shaft 74 (Figs. 3and D) supported by uprights 75 on a framework 76 which is carried bya diagonal brac: ing member 7 7 bolted to the bracket 48 and to the base plate 31 of the machine. Lever 39 73 has an arm 78 connected byylink 79 with a bell crank SO pivoted to the frame 76, the other varm of which' is connected by a link S1 with an arm 82 rigidly secured'to the hollow shaft G9 (Figs. 4, 9, .10, 11 and 12), `85

The lower end of the hollow shaft 69ers-, tends into the casing 51v and has xed there.- on a collar 83 on which the sector gear 68 is integrallyformed. The lever 73 therefore controls the position of the movable 9a clutch member 53. W'ith the clutch inem.- ber 53 out of contact With the clutch member 52 'the entire transmission mechanism is disengaged 'from the motor shaft 49, 50.

Chasersing.v moiicmentall7hen the clutch 95 member 53 is in engagement with the clutch member 52 the shaft 59, which is termed the A intermediate shaft, is driven in the same d direction as the shaft 50. This is acc-:om-4

plished by the following arrangements: The It sleeve 72 is formed with slots 84 into which the dogs 6l entend. As the dogs 61 are piv.-Y obed' to the pinion`54 which is feathered to the hub of the clutch member 53 the revolu.`

tion of the latter With'the fixed clutch'meml.

ber 52 revolves the sleeve 72. This sleeveis formed with gear teeth 85 Which mesh A with 'a gearwheel lS6 (Fig.' 10) turning stud -87 and meshing with a gear 88 (sec also Figs. 2 and 5) keyed to the'intermediate` 1i shaft The gear 88 'ineshes'with a gear 89 loose on the shaft 61 which corresponds n With.- the beforementioned- 'geaiGO Abut-fis driven in the opposite direction';7

'Mechanism fml rotating" the machines-.'- 1i Slidablyv mounted o'n the-main shaft 50 `is a collar 90 (Figs. 2, 5, 7 and 8) .formed :with two pairs of diametrvically arranged tapered slots 91, 91a respectively, into which project the heads ofscrews 92 carried byangular, 1:

arms 93, 93a pivoted to the'hub 94 o'f a clutch member 95 which isfiXed tothe shaft 50. The""`arms 93, 93 are formed With slo'ts 96 into which extend studs 97 on' the endof. rods 98 which pass' loosely. through op'h.- 1 ings in the fixed clutch-member 95 and rare threaded into a'ring 99 carried by a movable clutch member 100. The ltitter has a 'slight longitudinal' movement on the hub 101 of a shaft102 which projects out of the ,casing A1 51, the clutch member being held from rotation on the hub 101 by afeather 103. The clutch member r100 has twoh'clutch faces, one adapted to engage with the clutch face on 'the clutch member 95 and another adapted to .engage with a clutch face formed on va gear wheel 104 which turns on a bushing 105 in which the shaft 101, AO2 turns. The gear/ Wheel 104 is meshed by a smaller gear 106 keyed to the intermediate shaft 50. When the collar 90 is moved in one direction the movable clutch member 100 is clutched to the clutch member fixed tothe main shaft 50 and shaft 102 is given a forward revolution. `/Vhen the collar 90 is moved in the other direction the movable clutch-member is clutched to the gear wheel 104 which is constantly driven from the pinion 10G on the intermediate shaft 59 so that the shaft 102 is driven in the opposite direction to re- Verse the rotation of the machine.

The rotation of the machine from shaft 102 is effected by the following train of gears: Keyed to the shaft 102 is a gear wheel 107 which meshes witha. gear wheel 108 (Figs. 1, 5, 17 and 18) carried onv a shaft 109 provided at itsother extremity "with a bevel gear 110 meshing with a bevel gear 111 on a vertical shaft 112 which carries a pinion 11? meshing with a large lgear 1111 carried on the shaft 115 having at its upper end the pinion 40 which meshes with the cirx cular rack 29 on the rotatable frame of the machine.'

The collar 00 for shifting the movable clutch member 100 is moved back and forth on shaft 50 b v the following' mechanisn'i: Mounted on the shaft 711 (Figs. 1, 3 and fil is a lever 11T-the controlling lever for the mechanism for rotatingr the n'lachine-connectcd by a link 118 with a bell crank 119 lfigs. andy-"1) ]'iivoted'in a fork 120 on the hase of the frame T0 and connected by a link 121 with an arm 122 (see also Fig. 7) on a shaft 12? revoluhle 'in a vertical hearing llformefl on `lhe casing :il and in a hearing provided by a bracket 125 within the casing. (')n the shaft 122i between the bearings 121 and 125 is a collar 120 formed with avvolte 127. the forked extremities 12S of which (Fig. 5l extend around rollers '12!) on a ring revoluhly mounted in a groove in the collar 90.

These gear wheels are fmmed with the clutch faces 131, 131a adapted to be engaged by clutchy members 132, 132 which latter are 'provided with sleeves 133, 1.5333. the clutch members beingr slidably mounted on the shaft `61 but held from rotation by the feather 134. Pivoted 4to the clutch members 132, 132a are dogs 135, 135, the inner extremities of whiehanegigaged by the conical cam surfaces of a slidable collar 136. The outer ends of the dogs bear against rings 137, 137 fixed to the gears G0 and 89 respectively. Then the collar 1315 is moved from its central position one way or the other it engages one or other set of dogs and by rocking the dogs forces the clutch member vor 132,l

as the case may be, into engagement with the clutch face 131 or 1313.`
